The dominant species present in water if the ph is held constant at ph = 8 is $C_{6}H_{7}N,H_{3}O^{+}$ .

The pH scale is used in chemistry to determine whether an aqueous solution is basic or acidic. Historically, pH stood for "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.

A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave. The negative log base 10 of the hydronium concentration is used to define pH. The pH is a logarithmic indicator of how many hydrogen ions are present in a solution. Since pH is measured on a log scale, a pH increase of 1 equates to a 10x increase in the concentration of H+ ions.

How many molecules of lactate can one molecule of lactate dehydrogenase act on in 21 minutes?

USPshnik [31]

The turnover number (number of molecules the enzyme can act on per second) for lactase dehydrogenase is 1,000 lactate molecules per second.
In one minute, this becomes:

(1,000 molecules / second) * (60 seconds / minute)
= 60,000 molecules / minute

In 21 minutes, this will be:

60,000 * 21

= 1.26 x 10⁶ molecules of lactate

The reaction of 0.779 g K with O2 forms 1.417 g potassium superoxide, a substance used in self-contained breathing devices. Dete

zhannawk [14.2K]

First we need to find the number of moles of both K and O reacted
K - 0.779 g / 39 g/mol
= 0.02 mol
the mass of O₂ reacted = 1.417 g - 0.779 g = 0.638 g
O₂ moles = 0.638 g / 32 g/mol
= 0.02 mol
the number of both K and O₂ moles reacted are equal
therefore stoichiometry of K to O₂ reacted are 1:1
then the formula of potassium superoxide is KO₂
